OILING- SYSTEM FOR INTERNAL-COMBUSTION MOTORS.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed September 6, 1917. Serial No. 189,958;

To all whom it may concern:

Be it known that I, DANIEL B. MEDANICH, a. citizen of the United States, residing at Buechel, in the county of Jelferson and State of Kentucky, have invented a certain new and useful Improvement in Oiling Systems for Internal-Combustion Motors.

This invention relates to an oiling system for internal combustion motors, and an object is to provide means whereby oil from a central source of and continuously delivered to the valves, cylinders and bearings of such a, motor.

To the accomplishment of the foregoing and related objects, said invention consists of the means'hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and following de scription sets forth in detail certain mechanism embodying the invention, such disclosed means constituting however but one form in which the principle of the invention may be used.

In the drawing, wherein similar reference characters designate like parts in the several views, Figure 1, is a transverse sectional view of a motor embodying my invention: Fig. 2, a plan view of same. 7

As shown in the drawing, -10- designates a power cylinder which is mounted upon a crank case 11-, of approved construction, within which are mounted respectively, a piston -12- and a crank shaft 13, the latter being connected with the former by means of a connecting rod -14-, whereby motion is transmitted from the piston to the crank shaft. The motor illustrated is of the pattern popularly known as T head, exhaust and intake valve cylinders 15, 16 being disposed respectively on opposite sides of the power cylinder and communicating therewith by means of ports -17, 18-. A water jacket -19 envelops the power and valve cylinders. The valve cylinders are open at their lower ends to the atmosphere. In the upper end of each valve cylinder is an internal annular valve seat 20 in a line with, or just above the upper end of the power cylinder, against which, piston valves 21, 22-- close. Valve rods 23- are connected with the cylinders by suitable means such as ball joints -24- and depend therefrom into position to be ac supply will be positively tuated, to open the valves, through the medium of levers '-25, by means of cams -26-. The cams are secured on shafts -2'7 which receive motion from the crank shaft by suitable means such as belts 28. Springs -29 serve to return the valves to the closed'position, The inlet valve cylinder communicates at its upper end with a transverse passage 35 which extends across the head of'the motor, and at its outer end is provided with means such as a flange 36 for the attachment thereto of a conduit which leads to a suitable source of fuel supply. The passage 35 divides and passes around a well 37 within which is located a spark plug -38. An exhaust tube 39 leads from the upper end of the exhaust valve cylinder through the intake passage 35, the arrangement being such thatincoming fuel impinges upon said tube and is heated by contact therewith. An internal annular groove 40- provided in each valve cylinder is supplied with lubricating oil from a suitably positioned container 41, by means of conduits 42, 43-. Passages 44- lead from the grooves 40 in the valve cylinders to an internal annular groove -45 in the power cylinder. A tubular pin -46- which extends diametrically through the piston, is the medium whereby the connecting rod is joined therewith, and at each reciprocation of the piston as the open ends of the pin passes the groove 45, oil enters the pin and through an opening -'48 in the side thereof issues into a passage 49- which extends along the connecting rod and conducts the oil to the connecting rod bearing 50, illustrated herewith as being a ball hearing. The rapid movement of the balls, in the bearing, past the orifice of passage 49, creates a suction therein which causes a continuous flow of in a trough, or gutter, '52

the bearing, passes through openings 51 in the crank case into the compartments in Which" are the'cams, and servesto keep them properly lubricated. A portion of the oil, as it trickles down the walls, will be caught 7 ranged along the inner side of the crank case at a suitable distance above the level of the crank shaft. From the trough 52,

the oil flows, bya conduit-*53 to a point to without departing from the spirit of the invention or sacrlficlng any of 1ts advantages, and I therefore do not wish to restrict myself to the details of construction hereinbefore described, and as shown in the accompanying drawing, but reserve the right to make such changes, variations and modifications as come properly within the scope of the protection prayed.

Having thus described my invention so which is arthat those skilled in the art pertaining thereto 1 1 1 ay make and use the same, claim:

2 l. lnia motor as characterized, a valve cylmeans for supplying oil thereto, a power ()YlllldQillQNlIlg an internal annular groove,

P11183118 for leading oil thereto from the first named groove, a piston reciprocably mounted in the power cylinder, a tubular pin hav- 1 'ing a'lateral opening extending transversely through the piston, a connecting rod provided with a longitudinal oil passage movably positioned on said pin so that said passage registers with the lateral opening therein.

2. In a motor as characterized, a power cylinder having an internal annular groove, exhaust and intake valve cylinders disposed respectively on each side of said power cylinder, each of said valve cylinders having an internal annular groove, an oil container, means for delivering oil from said container to the grooves in the valve cylinders, means for leading oil from the grooves in the valve cylinder to that in the power cylinder, a tubular piston pin having a lateral opening, a connecting rod having a longitudinal oil passage, the entrance to which registers with said opening.
